两广交界地区180对反复自然流产夫妇染色体核型分析

Analysis of chromosomal karyotypes on 180 couples with repeated spontaneous abortions from border areas between Guangdong and Guangxi

目的 研究染色体核型异常与两广交界地区反复自然流产夫妇之间的关系。方法 对两广交界地区180对反复自然流产夫妇进行外周血染色体核型分析。结果 180对反复自然流产夫妇中,共出现染色体核型异常夫妇46对,染色体核型异常检出率为25.56%(46/180),46对异常核型中染色质多态变异25对(54.35%),染色体倒位11对(23.91%),染色体平衡易位7对(15.22%),罗伯逊易位1对(2.17%),染色体数目异常1对(2.17%),嵌合体1对(2.17%)。结论 染色体核型异常是导致两广交界地区育龄夫妇反复自然流产的重要危险因素之一。

Objective To investigate correlation between chromosomal karyotype abnormality and repeated spontaneous abortion of couples in the border areas between Guangdong and Guangxi. Methods Analysis of chromosomal karyotype in peripheral blood was performed in 180 couples with repeated spontaneous abortions in the border areas between Guangdong and Guangxi. Results Among 180 couples with repeated spontaneous abortion,46 couples had abnormal chromosome karyotype,detection rate of which was 25.56%(46/180).Among 46 couples with abnormal chromosome karyotype,25 couples(54.35%) had chromatin polymorphism variation,11 couples(23.91%) had chromosome inversion,7 couples(15.22%) had balanced translocation of chromosome,1 couple(2.17%) had Robertsonian translocation,1 couple(2.17%) had abnormal chromosome numbers,and 1 couple(2.17%) had chimera. Conclusion Chromosomal karyotype abnormality is one of the important risk factors for repeated spontaneous abortion in couples of childbearing age in border area between Guangdong and Guangxi.
